Abstract :
Power allocation with unequal strategy, is a technique to further enhance system performance in multiple access schemes. This paper is basically related with the performance enhancement of iterative IDMA systems using unequal optimum power allocation algorithm. Here, we compare the performance of coded and uncoded IDMA system with random interleaver & tree based interleaver. The simulation results demonstrate the superior performance of tree based interleaver in comparison to random interleaver in view of memory requirement along with similar BER performance.
